No I have not yet tried this.

Doing netstat queries means that I get 80000+ ip addresses on my server. Each 
of these addresses I would have to check against the list of relays to sort 
out connections to other relays and only do GETINFO ip-to-country to the 
remaining IPs. This sounds complicated and error-prone. Can't the ORCONN event 
be used to get a notification if a client connects?

Thanks for your help
